FLUSHING MECHANISM.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application led August 19, 1905. Serial No. 274,931.

To all whom 'it may concern:

Be it known that ALBERT SUocor, a citizen of the United States ofAmerica, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inFlushing Mechanisms, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements influshing mechanism for water closets, and the invention relates moreparticularly to that class of closets known as seat action closets, inwhich the flushing of the closet is produced by the raising and loweringof the seat of the closet.

The invention has for its object a novel form of flushing tank adaptedto be used in connection with a bowl or hopper, the inlet and outlet ofsaid tank being automatically controlled, by the raising and lowering ofthe seat of the closet.

Another object of this invention is to provide a novel form of flushingmechanism for closets which will be positive in its action, simple inits construction, and free from all danger of being injured by ordinaryuse.

lVith the above and other objects in view, which will more readilyappear as the nature of the invention is better understood, the sameconsists in the novel construction, combination and arrangement of partsto be hereinafter more fully described.

The essential features of the present invention are necessarilysusceptible to structural change without departing from the spirit andscope .of the invention, but the preferred embodiments of the inventionare illustrated in the accompanying drawings, wherein Figure 1, is aside elevation of a ho per or bowl equipped with my improved ushingmechanism, FiO. 2, is a vertical sectional view of a portion of themechanism, Fig. 3, is a rear elevation of a portion of the flushingmechanism as connected with the seat of a hopper or bowl, and Fig. 4, isa plan view of the hopper equipped with the actuating mechanism of theflushing tank.

In the drawing, 1 indicates a bowl of ordinary form, on which is hinged,as at 2, a seat 3, provided with a lid 4.

5 indicates the reservoir or tank, usually in the form of a large standpipe as shown.

6 indicates an elbow connection secured in the water inlet of the bowl.Mounted upon the vertical leg or arm of this elbow connection 6 is avalve casing 9 in which is received the threaded lower end 8 of thestand pipe 5, said stand pipe being provided adjacent its lower end witha ilange T seated on the upper end of the valve casing 9. similar valvecasing 19 is positioned upon the upper end of said reservoir 5 and isprovided with a centrally aperturcd partition, having the valve seat 20in the upper side thereof. The valve casing 9 is provided with acentrally apertured partition having the valve seat 10 in .its lowerside.

A valve rod 14 is mounted in the stand pipe extends into the valvecasing 19, through the valve casing 9, and through the ordinary arm orleg of the elbow 6, an aperture 13 being provided in said elbow for saidvalve rod, and suitable packing being placed in said aperture to preventleakage of the water therethrough. The lower end of the rod carries acup 14, which rests on a substantially elliptical shaped spring 16,carried by cross head 17 which connects the lower ends of two verticalrods 18a, attached at their upper ends to arms 1S which are carried bythe seat 3, being rigidly connected at the rear end of said seat.

On the valve rod 14 below the partition in the valve casing 9 is a valve15, adapted to seat, when the valve rod is elevated, with the valve seat10, and upon the extreme upper end of said valve rod is a valve 23adapted to normally seat with the valve seat 20 of the valve casing 19.

The seat 3 is adapted to remain normally in a slightly tilted positionas seen in Fig. 1 of the drawings, and the valves 15 and 23 are shown intheir normal position in Fig. 2 of the drawings, the valve 23 beingseated, and the valve 15 unseated.

Vhen the seat 3 is depressed into engagement with the bowl, the outerends of the arms 1S move upward, owing to the downward movement impartedto the forward part of the seat, the rods 1Saare elevated, and throughthe medium of cross head 1T and spring 16, valve rod 14 is elevated,forcing lvalve 15 against its seat, and unseating valve 28, whereby thewater from pipe 21 may iiow in to ill the stand pipe 5. Vhen, however,pressure upon the seat 3 is relieved, valve rod 14 descends by gravityand also by reason of the water against valve 23 as well as againstvalve 15, and valve 23 is seated, while valve 15 is simultaneouslyunseated, thus allowing the water contained Within the stand pipe 5 toflow into the bowl and flush the same.

It will be noted that the stand pipe constituting the reservoir is, inmy device, normally empty and, when the valve rod 14 is elevated asabove described, should the pressure of water delivered into the standpipe increase for any cause above the normal pressure, the valve rod byreason of its being yieldingly supported at its lower end by the spring16, will yield under such excess pressure so as to unseat valve l5sufficiently to permit the water to pass through to the bowl.

That l claim and desire to secure by Let ters Patent is In a flushingmechanism, the combination with a bowl, and a seat hinged thereto, of apair of arms connected to the rear edge of the seat and projectingrearwardly, an elbow connected to said bowl, a valve-casing supported onsaid elbow, and provided with an apertured partition having a valve seaton its underneath face, a stand pipe supported on said valve casing andcommunicating therewith, a valve casing mounted on the upper end of saidstand pipe having a central apertured partition provided with a valveseat on its upper face,a supply pipe communicating with said secondnamed valve casing, a valve rod extending through said elbow and standpipe, a valve on the upper end of said rod normally seated on the valve#seat in said upper valve casing, a second valve on said rod below thepartition in said lower valve casing and normally unseatedr from thevalve seat in said casing, vertical arms connected to the arms carriedby said seat on the bowl, a cross head connecting said vertical arms, aspring on said cross head engaged by the lower end of said valve rod,said valve rod being capable of longitudinal actuation for reversing thesaid positions ofV the valves, and said valves adapted to automaticallyreturn to their normal positions upon the existence of an excess of anypredetermined water pressure in said supply pipe.

In testimony whereof I affix my signature in the presence of twoWitnesses.
